Yes, with this command line it was not working. I remember I've seen 
ne2k-pci in dmesg, I also see (ifconfig) that it gets IP. The problem 
was that I've not been able to reach any remote side nor Solaris 11 
host. With this:

$HOME/sfw/qemu-2.2.0/bin/qemu-system-sparc64 -hda debian.img -nographic 
-m 1024 -net nic,model=virtio -net user

it was running fine. ANy host tested reachable. Honestly the problem 
with networking may be in the platform I've been using. And that is:

amd64 + Solaris 11, inside it running VirtualBox 4.3.16 with Ubuntu 
14.04 LTS on AMD64 and inside it Qemu 2.2.

Later I've been able to compile Qemu 2.2 on Solaris 11 so OpenBSD was 
run directly on Solaris 11/AMD64 + Qemu 2.2. This time neither ne2k-pci 
was working so I switched to i82551.

So it may be a little bit confusing, but as networking is running well 
now, I would consider this to be low priority...

Yes, in both cases I run qemu 2.2.
